Programmable Input Filtering Overivew Each of the BMX MSP 0200 PTO module inputs allows input filtering. There are four levels of filtering available (low, medium, high and none), that can be configured in the configuration screen, as shown: 112 EIO0000000058 10/2013
Description The filtering used is a programmable bounce filter, which operates as follows: Bounce rejection diagram In bounce rejection mode, the system delays all transitions until the signal remains stable for the duration defined for the filter level. Bounce rejection levels Input Filter Level Min Pulse Drive_Ready&Emergency, Counter_In_Position Proximity&LimitSwitch used as LimitSwitch Origin, Proximity&LimitSwitch used for homing No filter Low (For Bounces > 2 khz) Medium (For Bounces > 1 khz) High (For Bounces > 250 Hz) No filter Low (For Bounces > 2 khz) Medium (For Bounces > 1 khz) High (For Bounces > 250 Hz) No filter Low (For Bounces > 2 khz) Medium (For Bounces > 1 khz) High (For Bounces > 250 Hz) 2.3 ms 2.7 ms 3.5 ms 6.3 ms 2.1 ms 2.45 ms 3.25 ms 6.3 ms 60 μs 450 μs 1.25 ms 4.1 ms For each input, the bounce level to be applied is independently configurable by the user through the configuration parameters %KWr.m.c.2 and %KWr.m.c.3. EIO0000000058 10/2013 113
Event Sending to Application Summary The PTO channels can send events to the application. To do so in UnityPro configuration screen, enable the event functionality and specify the number of the event task that will be triggered. PTO channels support 2 sources of events: Position reached Referencing done All the events sent by the unit, regardless of the source, call the same single event task in the PLC. There is only one type of event signaled per call. The source producing the call is determined in the event task via the Event Sources variable (%IWr.m.c.12). This variable is updated at the beginning of the event task processing. NOTE: It is not recommended to send new PTO commands in Event Task, as they may be rejected. Enabling A source will produce its events if the corresponding enable bit is set to 1. This event source enabling is done through the implicit command object %QWr.m.c.0. Any event occurring while its source is disabled will be lost. When the source is enabled again, only new event occurrences will be produced. Object Type Symbol Value %QWr.m.c.0 INT Enable Evt Source One bit per source 1: Enable / 0: Disable x0 bit Position reached x1 bit Referencing done Limitations Each PTO channel can produce a maximum of one event per 2 ms, but this flow may be slowed by the simultaneous transmission of events by several units on the rack bus. NOTE: It is not recommended to send new PTO commands in Event Task, as they may be rejected. 114 EIO0000000058 10/2013
Special Input Interface The event has a unique input interface; this is only updated at the beginning of event task processing. This interface includes: Events Source variable (%Iwr.m.c.12). Position: the current position on event time. EIO0000000058 10/2013 115

Section 11.1 General Command Programming General Command Programming Overview This section deals with general programming features concerning the BMX MSP 0200 motion functions. What Is in This Section? This section contains the following topics: Topic Page Elementary function description 119 Command Mechanism 120 Motion Command Using FBD 121 Motion Command using Write_CMD 123 Command Mechanism Sending Rules 124 Parameter Description 125 Sequence of commands 128 Axis Status Information 130 118 EIO0000000058 10/2013
Elementary function description Elementary Functions There are 6 basic Motion Commands, which are sent by explicit exchanges: FrequencyGenerator (see page 133) MoveVelocity (see page 139) MoveAbsolute (see page 156) MoveRelative (seepage161) Homing (see page 187) SetPosition (see page 201) NOTE: The Stop command is sent by implicit exchanges. (see page 203) EIO0000000058 10/2013 119
Command Mechanism Overview There are two ways to send motion commands (other than Stop) from the user application: Using the specific Elementary Functions (EFs), in the Unity library Using the WRITE_CMD instruction PTO Elementary Functions The PTO EF family contains 6 instructions: Name Input CH Input 1 Input 2 Input 3 unsigned short FrequencyGenerator ANY_IODDT %CH DINT Target_Frequency unsigned short MoveVelocity ANY_IODDT %CH DINT Target_Velocity unsigned short MoveAbsolute ANY_IODDT %CH DINT Target_Position unsigned short MoveRelative ANY_IODDT %CH DINT Target_Distance DINT Target_Velocity DINT Target_Velocity unsigned short Homing ANY_IODDT %CH DINT Position DINT Velocity unsigned short SetPosition ANY_IODDT %CH DINT Position BYTE BufferMode BYTE BufferMode Stop Command There is a specific mechanism to send Stop commands, which uses implicit exchanges. When the axis needs to be stopped, the specific implicit command object: "Stop Level" (%Qr.m.c.2) must be set to 1. A Stop command takes precedence over any other motion commands: any command sent while the axis is stopping will be rejected. 120 EIO0000000058 10/2013
Motion Command Using FBD At a Glance The first way to send a motion command is by using the specific Elementary Functions (EFs), in the Unity library For example: the EF MoveAbsolute EN/ENO Pins In order to make the EN and ENO pin appear in the FBD representation double click on the FBD representation (or right click and select properties) and check the Show EN/ENO checkbox. EN and ENO are general pins used by all EFs. The ENO pin is computed only if EN is set to 1, otherwise its value is undefined. The output pin CMD_NB is computed internally. There are 3 different cases: If the command has been correctly sent and accepted, this object will give a command number (between 0x01 and 0x7F), and can be used to follow the status of the command through the implicit status objects (%IWr.m.c.0 to %IWr.m.c.5). The ENO output of the EF is set to 1. If the command has been correctly sent but rejected, CMD_NB takes the value of the command number for the first 7 bits, but its most significant bit will be set to 1 (value between 0x81 and 0xFF). The ENO output of the EF is set to 1 If the command has been incorrectly sent, CMD_NB will remain at 0. The ENO output of the EF is set to 0 In the last two cases, an error notification will be reported through the CMD_ERR system object (%MWr.m.c.1.1). EIO0000000058 10/2013 121
NOTE: It is necessary to have EN set to 1 to change command parameter values. WARNING UNEXPECTED PARAMETER CHANGES Command parameters will change on each PLC cycle if EN is set to 1. Add a rising edge detection (R_Trig) as shown on the diagram below: Failure to follow these instructions can result in death, serious injury, or equipment damage. Other Pins The input pins correspond to all command parameters associated with this specific command. (except the command code) When the command is sent through the PTO EF, the %MWr.m.c.13 object takes the same value as CMD_NB. 122 EIO0000000058 10/2013
Motion Command using Write_CMD At a Glance It is also possible to directly write the parameter values into the corresponding %MWCmd objects and then trigger the execution of the motion command by sending a WRITE_CMD instruction. Description The behavior is similar to the one with EFs. However, it is necessary to specify what kind of command is to be executed with the command code byte. If this parameter is not valid, the command will be rejected and the detected error will be reported in the CMD_CODE_INV status object (%MWr.m.c.3.2). When sending a command through WRITE_CMD, the command object %MWr.m.c.13 is computed internally. Its behavior is exactly the same as the CMD_NB output pin of the EF when the command is sent by EF. This mechanism can be used to send motion commands from Unity Operator Screens (see Unity Pro, Operating Modes), which can t be done with only EFs. NOTE: A command example, written in ST representation is given for each EF. (seepage131) EIO0000000058 10/2013 123
Command Mechanism Sending Rules At a Glance Independent of the method used to send a command, certain constraints must be taken into account: Only one command can be sent at a time (at most one command per PLC cycle). The previous command needs to be received by the channel before sending a new one. Any command sent while another one is being exchanged with the channel will be ignored. The availability can be checked on the bus rack through the system bit CMD_IN_PROGR (%MWr.m.c.0.1). The channel can receive two commands in succession. One will be executed, while the second is in buffer, waiting for the first one to be completed. This is valid for positioning commands only, and the chosen buffer mode must be Buffered or BlendingPrevious. When a command is being executed, and another one is already in buffer, the channel cannot accept a third command. Check the availability of the channel before sending any command. If a command is sent while the channel is not available, it will be rejected, all commands in the channel will be aborted, the axis will be stopped and the corresponding error notification will be reported in the BUFFER_FULL status object (%MWr.m.c.3.4). Module Availability to Commands The value of implicit status objects: Idle and FreeCmdBuf allows to check if the module is available for a new command. The following table details the different cases: Idle FreeCmdBuf Meaning 0 0 Two cases: A command is being sent A command is being executed, and another one is in buffer In both cases, no command should be sent. 0 1 A command is being executed, but the command buffer is free. A new command can be sent and will be kept in the command buffer; FreeCmdBuf is set to 0. 1 0 No significance 1 1 The buffer is free and no command is being executed. A new command can be sent. 124 EIO0000000058 10/2013
Parameter Description Overview Each command has its related command parameters, setting parameters and adjustment parameters (refer to each function for more details). Command Parameters Command parameters can be set in the application: directly in the interface objects, previous to executing the Write_Cmd instruction by executing EFs NOTE: Sending a new command of the same type aborts the active command. NOTE: It is not possible to modify the command parameters of a Homing command, since it does not support the succession of several commands. (see page 124) Setting Parameters Setting Parameters are only managed through the Unity Pro configuration tool. Adjustment Parameters Adjustment Parameters are managed through the Unity Pro Adjust tool. They can be read by executing the Read_Param instruction and their initial values can be set to their current values by executing the Save_Param instruction. They can be set by modifying %M.. objects and executing the Write_Param instruction executing the Restore_Param instruction to set them to their initial values. When accessing the Adjustment Parameters: through the IODDTs or the Adjustment screen, it is possible to directly write the unsigned values. through their topological addresses, only signed types are accepted. Converting the unsigned value into a signed value before writing in the %MWr.m.c object is necessary. If Adjustment Parameters are changed while the PTO channel is running, this change will take effect on next commands. EIO0000000058 10/2013 125
Limit Parameters These are objects used to define valid ranges of values for command parameters. Configuration Parameters Object Type Symbol Description %KWr.m.c.4 UINT Max Acceleration Acceleration Rate Maximum Value %KWr.m.c.5 UINT Max Deceleration Deceleration Rate Maximum Value %KDr.m.c.6 UDINT Max Frequency Maximum Frequency (in Hz) %KDr.m.c.8 DINT SW Max High Limit Software Pulse Number Maximum High Limit %KDr.m.c.10 DINT SW Min Low Limit Software Pulse Number Minimum Low Limit Adjustment Parameters Object Type Symbol Description %MDr.m.c.14 UDINT SW High Limit Software Pulse Number High Limit %MDr.m.c.16 UDINT SW Low Limit Software Pulse Number Low Limit Any command sent with parameters that are inconsistent with the specified limits will be rejected. 126 EIO0000000058 10/2013
Constraints on Configuration and Adjustment Parameters: The following rules of consistency between configuration and adjustment parameters must be observed: SW High Limit SW Max High Limit SW Max High Limit > SW Min Low Limit SW High Limit > SW Low Limit SW Low Limit SW Min Low Limit Start Frequency Max Frequency Stop Frequency Max Frequency Homing Velocity Max Frequency Start Frequency Homing Velocity if Start Frequency enabled Stop Frequency Homing Velocity if Stop Frequency enabled Acceleration Rate Max Acceleration Deceleration Rate Max Deceleration Emergency Deceleration Rate Max Deceleration If a setting parameter or initial parameter does not respect one of these rules, the configuration will not be accepted. NOTE: Unity Pro Initial parameters respect all the rule above. If an adjustment with an invalid parameter is set: The parameter will be rejected The previous values will be maintained The detected error will be reported in the ADJUST_FLT status word (%MWr.m.c.4) EIO0000000058 10/2013 127
Sequence of commands Motion State Diagram Any sequence of commands must respect the following state diagram: 128 EIO0000000058 10/2013
Allowed Sequence of Commands The PTO channel can accept the following sequence of command: Next Command No Command Current Command Frequency Generator Move Velocity Move Absolute Move Relative Homing Set Position No Command Reject Reject Reject Reject Reject Reject Reject Frequency Accept Accept Accept Accept Accept Reject Reject Generator MoveVelocity Accept Accept Accept Accept Accept Reject Reject MoveAbsolute Accept Accept Accept Accept Accept Reject Reject (Abort) MoveAbsolute (Buffered/Blending) MoveRelative (Abort) MoveRelative (Buffered/Blending) Accept Reject Reject Accept Accept Reject Reject Accept Accept Accept Accept Accept Reject Reject Accept Reject Reject Accept Accept Reject Reject Homing Accept Reject Reject Reject Reject Reject Reject SetPosition Accept Reject Reject Reject Reject Reject Reject Reject: The sequence of commands described in the cell is not supported. The new command will be rejected. All commands in progress will be aborted, the axis will be stopped and an error notification will be reported in the CMD_SEQ_INV status object (%MWr.m.c.3.3). Accept: The sequence of commands described in the cell is supported. The new command is accepted. Its execution starts either immediately, or after the completion of current command, depending upon the set buffer mode. The BufferMode command parameter is used to determine how a sequence of commands will be executed: Abort: the new command aborts the current command. Buffered: the new command is executed after the current command is completed. BlendingPrevious: the two commands are merged at the target velocity of the first command. For each buffer mode, the behavior is detailed in MoveRelative description. (seepage161) EIO0000000058 10/2013 129
Axis Status Information At a Glance In order to know which PLCopen state the axis is in, check the value of the AXIS_STS object (%IWr.m.c.6). Axis Status This word does not describe all the PLCopen states that appear in the state diagram, but it indicates which of the following 4 states the axis is in: STANDSTILL state is described with the following set of information: STOPPING state is described with the following set of information: ERROR_STOP state is described with the following set of information: Command in execution. This is not a PLCopen state but includes several of them. It is described with the following set of information: bit0 (MOVING) = 0 bit1 (STOPPING) = 0 bit3 (AXIS_FLT) = 0 %IWr.m.c.0 = 0 & %IWr.m.c.7.bit0 = 1 (no command in execution) %IWr.m.c.1 = 0 & %IWr.m.c.7.bit1 = 1 (no command in buffer) bit1 (STOPPING) = 1 bit3 (AXIS_FLT) = 0 %IWr.m.c.0 = 0 & %IWr.m.c.7.bit0 = 1 (no command in execution) %IWr.m.c.1 = 0 & %IWr.m.c.7.bit1 = 1 (no command in buffer) bit1 (STOPPING) = 1 bit3 (AXIS_FLT) = 1 %IWr.m.c.0 = 0 & %IWr.m.c.7.bit0 = 1 (no command in execution) %IWr.m.c.1 = 0 & %IWr.m.c.7.bit1 = 1 (no command in buffer) bit1 (STOPPING) = 0 bit3 (AXIS_FLT) = 0 %IWr.m.c.0 0 & %IWr.m.c.7.bit0 = 0 (command in execution) bit0 (MOVING) = 1 This word (%IWr.m.c.0) indicates the exact PLCopen state: Each command sent has an allocated number and can be read through the CMD_SENT_NB (%MWr.m.c.13) object or the EF output. Knowing these two numbers, it is possible to identify which command and which type of profile is currently being executed and which state the axis is in (CONTINUOUS MOTION, DISCRETE MOTION and HOMING). This information can also be obtained using the Cmd_Status function. (seepage204) NOTE: When Drive_Enable is disabled, the axis referenced bit is cleared and any command can be accepted. 130 EIO0000000058 10/2013

Absolute Positioning: Move Absolute Description This function is used to manage a complete movement of the axis from the current position to a specified target position. The target position is directly specified with its coordinate, in pulses, relative to a previously set origin. The velocity of the axis will follow a trapezoidal profile: NOTE: No absolute positioning command can be performed while "REFERENCED" is low.

Positioning Buffer Mode Management At a Glance While a positioning command is running, it is possible to send a new command. The sequence of those two commands can be managed in three different ways according to the BufferMode parameter of the new command: Abort: the new command aborts the previous one and is executed immediately. Buffered: the new command is put into a buffer and executed only once the current command is completed. The current command ends normally (stops when reaching the target position). BlendingPrevious: the new command is put into a buffer and executed only once the target position of the current command is reached. However, the axis does not stop between both commands and the velocity is blended with the target velocity of the current command (see diagram below). 172 EIO0000000058 10/2013

Homing Description This function commands the axis to search for a reference point set by input signals, and to stop at this reference point. When the homing sequence is completed: The reference point s coordinate is set to the position value (parameter of the homing command) The channel "REFERENCED" status bit is set to 1 which activates software limits if not disabled. There are different homing modes, depending on the physical configuration of the controlled machine. The mode to be used is chosen via the "Homing Type" parameter (cf. description of each type below).

General Homing Features At a Glance There are 6 homing modes: Short Cam (see page 193) Long Cam Positive (see page 194) Long Cam Negative (see page 195) Short Cam with Positive Limit (see page 196) Short Cam with Negative Limit (see page 198) Short Cam with Marker (see page 200) Each homing mode has two velocities: a high velocity, which is set as a command parameter (Velocity), and a low velocity, used to get to the referenced point, set by adjustment (Homing Velocity). Homing I/O Settings Homing I/O settings When the Counter_Clear output is enabled (value 1): In order to synchronize the PTO channel and the drive, a pulse is sent on the Counter_Clear output. When the homing condition is reached, the channel s internal counter is set to the specified position value and the output frequency is stopped. The channel "REFERENCED" status bit is then set to 1. When the Counter_in_Position input is enabled (value 2): After the homing condition is reached, the output frequency is stopped. In order to synchronize the PTO channel and the PTO drive, the homing command remains running (BUSY state) until a rising edge of the Counter_in_Position input is detected. The channel s internal counter is then set to the specified position value and the channel "REFERENCED" status bit is set to 1. A homing function error is reported if Counter_in_Position remains low after a certain duration (time-out value to be configured in setting parameters) by rising the HOMING_FLT bit (%MWr.m.c.5.4) and the AXIS_FLT bit (%IWr.m.c.6.3). When no specific I/O are used for the homing process (value 0): When the homing condition is reached, the channel s internal counter is set to the specified position value and the output frequency is stopped. The channel "REFERENCED" status bit is then set to 1. Synchronization between the PTO channel and the PTO drive cannot be assumed because the end of the homing process is defined internally in the module, independently from any feedback from the drive. For all homing modes described in the following sections, the direction (FORWARD, BACKWARD) is given by the sign of Velocity, specified in the homing command. 192 EIO0000000058 10/2013
Homing Mode: Short Cam Short Cam In the Short Cam homing mode, the reference point is preset at the negative side of the cam, when coming in positive direction (off cam) at low velocity. Inputs used: The Short Cam homing mode only uses the Origin input (Cam). Detected errors that can be encountered: If a limit is bypassed and detected with Proximity&LimitSwitch input (if not disabled), the detected error is reported in the LIMIT_FLT status object (%MWr.m.c.5.1). If the axis is already on the cam at start, the homing function will not be executed and the detected error is reported in the HOMING_FLT status object (%MWr.m.c.5.4). If Drive_Ready&Emergency goes off (if not disabled), the detected error is reported in the DRIVE_KO status object (%MWr.m.c.5.0).

Homing Mode: Long Cam Positive Long Cam Positive In Long Cam Positive homing mode, the reference point is preset at the negative side of the cam, when coming in negative direction (from the cam) at low velocity. Inputs used: The Long Cam Positive homing mode only uses the Origin input (Cam). Detected errors that can be encountered: If a limit is bypassed and detected with Proximity&LimitSwitch input (if not disabled), the detected error is reported in the LIMIT_FLT status object (%MWr.m.c.5.1). If the axis is off the cam and direction is set backward (negative velocity), the homing function will not be executed and the detected error will be reported in the HOMING_FLT status object (%MWr.m.c.5.4). If Drive_Ready&Emergency goes off (if not disabled), the detected error is reported in the DRIVE_KO status object (%MWr.m.c.5.0).

Inputs used: The Long Cam Negative homing mode only uses the Origin input (Cam). Errors that can be encountered: If a limit is bypassed and detected with Proximity&LimitSwitch input (if not disabled), an error is reported in the LIMIT_FLT status object (%MWr.m.c.5.1). If the axis is off the cam and direction is set forward (positive velocity), the homing function will not be executed and an error will be reported in the HOMING_FLT status object (%MWr.m.c.5.4). If Drive_Ready&Emergency goes off (if not disabled), an error is reported in the DRIVE_KO status object (%MWr.m.c.5.0).

Homing Profile: Short Cam with Positive Limit Short Cam with Positive Limit In the Short Cam with Positive Limit homing mode, the reference point is preset at the negative side of the cam, when coming in positive direction (off cam) at low velocity. The Short Cam with Positive Limit homing mode uses the two homing-specific inputs: The Proximity&LimitSwitch input: used as the positive limit signal. On the rising edge of the signal (negative side), the axis decelerates to change direction. The Origin (Cam) input. 196 EIO0000000058 10/2013
Detected errors that can be encountered: If the axis is already on the cam at start, the homing function will not be executed and the detected error is reported in the HOMING_FLT status object (%MWr.m.c.5.4). When the axis is inside the working area (delimited by LimitSwitch signal) and direction is set backward (negative velocity), the homing function will not be executed and the detected error will be reported in the HOMING_FLT status object (%MWr.m.c.5.4). If Drive_Ready&Emergency goes off (if not disabled and Drive_Enable output is active), the detected error is reported in the DRIVE_KO status object (%MWr.m.c.5.0). The detected errors are also reported in the AXIS_FLT implicit status object (%IWr.m.c.6.3). NOTE: During the homing process, the Proximity&LimitSwitch input will not be used as Limit Switch (no detection of limit crossing). For any other command, this input can still be used as Limit Switch input. EIO0000000058 10/2013 197

Homing Mode: Short Cam with Marker Short Cam with Marker In the Short Cam with Marker homing mode, the reference point is preset at the negative side of the zero marker, when coming in positive direction at low velocity. The Short Cam with Zero Marker homing mode uses the two homing-specific inputs: The Proximity&LimitSwitch input: used as the proximity signal. On the falling edge of the signal, the axis decelerates to change direction. The Origin input used as Zero Marker signal. The detected errors that can be encountered: If Drive_Ready&Emergency goes off (if not disabled and Drive_Enable output is active), the detected error is reported in the DRIVE_KO status object (%MWr.m.c.5.0). The detected errors are also reported in the AXIS_FLT implicit status object (%IWr.m.c.6.3). Limit crossing detection: The Proximity&LimitSwitch input can not be used as a Limit Switch input, either for homing commands or any other command. Instead use the Drive_Ready&Emergency input in order to detect a limit-crossing event. (see page 32) 200 EIO0000000058 10/2013
Set Position Description Contrary to the other motion functions, this function does not impact the physical pulse outputs of the channel, and does not generate any motion profiles. Like the homing function, it defines an origin and a reference position of the axis by assigning an absolute coordinate to the current position of the axis and setting to 1 the channel "REFERENCED" status bit. This function can only be used when the axis is in STANDSTILL state. Physical Inputs/Output Input/Output Counter_Clear output Description To be connected to the corresponding input of the drive. When the Counter_Clear output is enabled, the Set Position function also orders the drive to reset its internal counter. Configuration Parameters Parameter Homing I/O Settings Valid Values Value 0: No I/O used (Default) Value 1: With Counter_Clear Output Value 2: With Counter_in_Position Input: not used with SetPosition command.

STOP Description Whatever the motion in progress, and at whatever stage of the movement, the user can order the axis to stop, smoothly, by going through a deceleration phase. It is also possible to STOP the axis by setting to 0 the Drive ENABLE command, then the moving part is forced to stop through a deceleration phase (equal to Stop command) Configuration Parameters Parameter PTO Output Mode Deceleration Unit Valid Values Value 0: Pulse + Direction (Default) Value 1: CW/CCW Value 2: A/B Phases Value 3: Pulse + Direction Reverse Value 4: CW/CCW Reverse Value 5: A/B Phases Reverse ms (default) or Hz/2ms Representation The stop function does not have any program representation, it can be activated via the debugging screen (see page 216) (Stop Level Cmd %Qr.m.c.2). Adjustment Parameters Parameter Stop Frequency (in Hz) Deceleration Rate Emergency Deceleration Rate Valid Values 0 Hz to 65,535 Hz, default is 0 Hz, limited by Max Frequency 10 to 32,500, default is 100, limited by Max Deceleration 10 to 32,500, default is 100, limited by Max Deceleration EIO0000000058 10/2013 203
Command Status Follow-Up Description There are two ways for the user to get the information about the status of a command: directly through the implicit objects %IWr.m.c.0 to %IWr.m.c.5. via the Cmd_Status DFB Representation in FBD Representation: NOTE: The command status follow-up is the only PTO function which doesn t need to be enabled (via EN input) in FBD representation. NOTICE UNINTENDED EQUIPMENT OPERATION Link the motion bloc output to the CMB_NB input of the CMB_status DFB through an intermediate static byte value. Failure to follow these instructions can result in equipment damage. 204 EIO0000000058 10/2013

Input/Output Description Inputs description: Name Type Description Channel T_PTO_BMX The IODDT of the PTO channel to which the command has been sent. This pin is also repeated as an output of the block. Cmd_Nb BYTE The number of the command. This object corresponds either to: The output of a PTO EF The CMD_SENT_NB (%MWr.m.c.13) object converted to BYTE type - after use of the WRITE_CMD instruction. Outputs description: Name Type Description Done BOOL The command has been executed and completed successfully Busy BOOL The command has been accepted by the PTO channel but is not completed yet. Active BOOL The command is being executed. CommandAborted BOOL The command has been aborted before completion. Error BOOL An error has been detected before the command completion. The boolean outputs "Done", "Busy", "CommandAborted" and "Error" indicate the current status of the command. As required by the PLCopen standard, these outputs are mutually exclusive: only one will be set TRUE at a given time. NOTE: If Cmd_Nb is different from 0, at least one of these outputs will be TRUE, except during one PLC cycle when all outputs will be FALSE, immediatly after the Cmb_Nb input value is modified. For buffered commands: when the command is in buffer (not yet in execution), Busy is TRUE. when the command is being executed, Active is TRUE. For non-buffered commands, the values for Active and Busy are TRUE when the command is being executed. NOTE: The DFB outputs will remain unchanged as long as there is no change in the status of the specified command or up to the moment the command number is re-used by another command. If, after a periode of time a new command is sent that has the same command number, the outputs of the DFB will then change to reflect the status of this new command. 206 EIO0000000058 10/2013

Slack Correction At a Glance The adjustment parameter Hysteresis (Slack) is used to define the number of output pulses to ignore from the position after every change of direction. Configuration Procedure To apply a slack correction, it is necessary to follow this procedure in order to configure it properly: Step: Action: 1 Set the Slack Correction value and validate the change. The Slack Correction will be activated if value is different than 0. 2 Before sending a command, it is necessary to reference the axis (SETPOSITION is not enought). 3 The system will automatically take in account the slack value for the following commands. Illustration When the configured pulse output mode is A/B phases (either normal or reverse), a hysteresis can be applied when changing direction. The behavior will then be as follows: Slack correction: 212 EIO0000000058 10/2013
